First I created a fractal image first, adjusting it until I got the corona the way I wanted it.Then I used a lensing effect on it to create the flaring, and an empty-ish spot in the center. I used mask selection on the empty spot, inverted the selection so the ‘corona’ area was protected from alteration. I then painted some flame/fire into the unmasked area. After it was filled, I ‘spun’ it slightly to using a rotate selection tool built into the program until I got the flame pattern such as it is.

Unmasked the entire image, and saved it as a TIFF. Opened file in Photoshop, proofed it, removing any aberrations or ‘bumps’ outside of the globe to make a flawless sphere in the center with clone stamp tool.
